A recent study claim that 45% of the population of all college students prefer printed textbooks to electronic textbooks. Do you want to test this claim by serving a random sample of 45 calls students. All the steps below to construct a 90% confidence interval

V Number Proportion Prefers printed textbooks to electronic Take Sample 27 0.6 textbooks Does not prefer printed textbooks to 18 0.4 electronic textbooks Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 90% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute". Sample size: X ? 45 Standard error: Critical values Point estimate: M 20.005 =2.576 Margin of error: Z0.010 =2.326 Critical value: 20.025 = 1.960 90% confidence interval: Zo.050 = 1.645 Compute Zo.100 = 1.282 (b) Based on your sample, graph the 90% confidence interval for the population proportion of all college students who prefer printed textbooks to electronic textbooks. . Enter the values for the lower and upper limits on the graph to show your confidence interval. . For the point (), enter the claim 0.45 from the study
